My 73 1.7L still has fuel delivery problems as I accelerate from 3700 to 4000 RPM. It's ok otherwise. I've done everything I can think of. has anyone ever had this problem?

Does the car shudder when you're going down the freeway at 3800rpms at a steady speed? If so then it's most likely the TPS (throttle position sensor).

TPS or,,,,

MPS (which was my problem)

had same problem check your dizzy. I had a bad spring

Check you dizzy!
